• What's the difference between converting mixed numbers to improper fractions and changing mixed number to an improper fraction?
• There is no difference. Converting and changing are two words for the same thing.
• I don't get anything in this video. Is there a easier way to do this?
• Take the denominator and multiply it by the Whole and add the numerator and keep the same denominator
• It is good for me. I can learn better.
• Are you feeling confident with this? I would recommend going a level up and going a bit harder. 🙂🙂
• A turtle is 20 5/6 inches below the surface of a pond. It dives to a depth of 32 1/4 inches. What is the change in the turtle's position?
• 32 1/4 - 20 5/6 = 11 5/12
The change in the turtle's position is 11 5/12 inches. Hope I helped, btw I love turtles 🐢:)

• Hi there! So writing mixed numbers as a improper fraction is pretty simple once you know how to do it.

For starters you have to have a mixed number to turn into an improper fraction. Take 3 1/2 for an example. The first thing you are going to do is do 2*3 because in the three, you have 6 halves. Then you will want to add it to the one because it you can't forget the half that was already there. Then you end up with the answer- 7/2
This also works with bigger numbers as well.

Hope this helps,

• Why does it always need to be a improper fraction? It is a improper fraction before we even change it! :(
• Its just to practice your skills converting between mixed and improper
